Most metals are not magnetic but iron is why?

1 answer:

5 0

This is because of the way that the electrons in an atom of iron behave. The electrons in an iron atom tend to have the ability to align themselves and face one toward one direction such that one side of the atom has high negative charge and the other side has a high positive charge. So then that atom will behave like a tiny magnet.

Now when many of these "tiny magnets" line up, their combined attraction creates the force known as magnetism.

Most other elements do not have this unique property that iron has and that is why they are not magnetic.

Theo made a list of the properties of electromagnetic waves. Identify the mistake in the list. Electromagnetic Wave Properties 1

lapo4ka [179]

Answer:

Line 3 has a mistake.

Explanation:

Electromagnetic waves consist of oscillations of electric and magnetic fields that oscillate perpendicular to the each other. Therefore, Line 1 is correct.

Also, the fields in an electromagnetic waves oscillate perpendicular to the direction of propagation of the wave: therefore, they are transverse waves. So Line 2 is also correct.

Electromagnetic waves, contrary to mechanical waves, do not need a medium to propagate: so, they can also travel through a vacuum. Therefore, Line 3 is wrong.

Finally, all electromagnetic waves travel through a vacuum at the same speed, called speed of light:

$c=3\cdot 10^8 m/s$

So, Line 4 is also correct.

What is the answer to this problem

vredina [299]

420 m of total distance is covered by the skier on travelling from A to D.

Explanation:

As from the picture, it can be seen that first the skier moved from position A to position B. And the distance covered by this movement is 180 m. Then as the skier travels from position B to position C, the distance between these two positions is 140 m from the figure. As distance is a scalar quantity, the direction is not taken into consideration. So only the magnitudes of the distance between those points are added.
